The James Webb Space Telescope is weighing in on a longstanding debate over why we don’t see more of the most massive red supergiant stars go supernova. NASA/ESA/CSA/Northrop Grumman In recent years, ...

Astronomers using JWST have captured the clearest view yet of a doomed red supergiant star just before it exploded, solving a ...

Astronomers have discovered a vast and expanding bubble of gas and dust surrounding a red supergiant star—the largest structure of its kind ever seen in the Milky Way. The bubble, which contains as ...

A giant bubble of gas and dust surrounds the red supergiant DFK 52, likely created in a powerful outburst 4,000 years ago. Astronomers are baffled at how the star survived without going supernova, and ...

Astronomers using the James Webb Space Telescope (JWST) have made a rare and groundbreaking discovery. For the first time, scientists were able to observe a red supergiant star not just after it ...

Astronomers have long searched for clues that a hidden companion star sits out of view near the red supergiant star Betelgeuse. Now, they’ve uncovered a new piece of evidence: a trail like the wake ...

What can an exploding star in a distant galaxy teach scientists about red supergiants? This is what a recent study published in The Astrophysical Journal Letters hopes to address as a team of ...

Red supergiant DFK 52 and its surroundings as seen by ALMA. The vast, complex bubble blown by this extreme star is about 1.4 light years across, thousands of times wider than our Solar System. ALMA ...
